Filed: 1989-01-27
Abstract: PURPOSE:To permit the sure cleaning of a paper feeding mechanism utilizing frictional force and the inside of a paper feeding device by allowing an adhesive sheet to pass similarly in case of the common passing of paper. CONSTITUTION:In order to recover the frictional coefficient of a conveyor belt 5, a cleaning sheet 29 into which an adhesive tape 28 having the slightly larger width than the conveyor belt 5 is applied is allowed to pass on a pasteboard 27 similarly as in case of a common paper, and the graphite powders accumulated on the conveyor belt surface are stripping-removed by the adhesive force. Further, the width of an adhesive tape 28' is set equal to the width of a read-out glass 7 and allowed to pass, and then the paper dusts 30 scattered on the read-out glass 17 are adhesion-removed, and also the foreign materials on a sheet guide surface and a roller surface can be removed at the same time, besides on the read-out glass 17. Thus, the paper feeding device can be cleaned without using other tools in the simple work.

Title: Monitor circuit for memory back-up primary battery
Inventor: YOSHIDA AKIO
IPC: G06F1/28
Filed: 1989-01-27
Abstract: PURPOSE:To prevent the burst of a primary battery due to the charging by monitoring the short trouble of a diode used for prevention of the charging applied from a commercial power supply via a monitor circuit for battery voltage and producing an alarm if the battery voltage exceeds its set upper limit level at the time of troubling. CONSTITUTION:A Zener diode 56 is connected from a constant voltage power supply via a resistance 58 to stabilize the reference voltage, and this joint (point B) is connected to the input of the other side of a comparator. In such a case, however, the reference voltage does not require so high strictness therefore can be acquired via a resistance voltage divider by using a resistance in place of the diode 56. The output terminal of a comparator 72 is connected to an alarm circuit 80. Then, the output is produced at the output terminal when the voltage obtained at a joint (point A) between a diode 54 and a limiting resistance 52 is higher than the voltage secured at the point B. The circuit 80 actuates an alarm to warn the necessity of repairs in case the output of the comparator 72 is confirmed. Thus it is possible to prevent the bursting of a primary battery.

IPC: G11B3/10
Filed: 1980-02-15
Abstract: PURPOSE: To increase the damping coefficient of record player as well as lower its Q value by using an elemental material obtained by dispersing graphite particles into Al or an Al alloy.  
     CONSTITUTION: A mother material is manufactured by uniformly dispersing graphite particles, particularly flaky graphite particles, into molten Al or a molten Al alloy. After being hardened directly or indirectly after gradual cooling, the mother material is again melted and then cast in a mold or made into a thin plate, followed by a cold or hot rolling process, in order to obtain a nonvibratory part for a record play. The record player-constituting material is excellent in lightness, damping characteristics, mechanical processability, and solid lubricity. Also, the use of the material enables one to suppress adverse influene on sounds due to the lowering of Q value at resonance frequency because of its excellent damping characteristics.
